China's laws have represented the will of the ruling class since they were born at that time, and they still do. But in the era when there was an emperor, the emperor was the representative of the ruling class and the highest authority, and had the right to change the laws of the country. "Gold words and jade words" not only show that you are joking, but also emphasize that every word of the emperor has legal effect, which is also one of the legal sources of China since ancient times. In addition to the ready-made laws formulated and promulgated by the law-making department, the emperor's instructions and language are also the source and supplement of laws, and the laws of the previous emperor era can be traced back.
Even in the era of British monarchy, local courts often asked the king to decide cases, which is a form similar to case law.
Therefore, the emperor has enough rights and qualifications to change the laws of the country, or to break the law and trample on the law. So much for the difference between a so-called bad king and a good king.
